MECHANISM FOR VIBRATING DOFFER-ROLLS.

SPECIFICATION forming part of Letters Patent No. 576,262, dated February2, 1897.

Application filed. April 15, 1896.

T0 at whom it may concern Be it known that we, JOHN FENNESSEY and JOHNM. PILLING,of the city of Cohoes,county of Albany, and State of NewYork, have invented a new and useful Improvement in Mechanisms forVibrating Doffer-Cylinders, of which the following is a specification.

Our invention relates to a mechanism for vibrating the doffer-rollers ofa carding-inachine by which when used for producing rovings having mixedcolors from rovings or slivers having differing colors the measure ofhorizontal movement imparted to the dotfer-rollers may be regulated by amechanism which is adjustable.

Accompanying this specification, to form a part of it, there are twoplates of drawings containing two figures illustrating the applicationof our invention, with the same designation of parts by letter referenceused in all of them.

Of the illustrations, Figure 1 is a front elevation of a carding-machinecontaining our improvement; and Fig. 2 is an end elevation of the same.

The several parts of the apparatus thus illustrated are designated byletter reference, and the function of the parts is described as follows:

The letter O designates the main cylinder, having the usual covering ofcard-clothing.

The letter O designates the fancy roll, having straight teeth, and D andD the dofierrollers, each of which is covered with carding-rings R. Eachof these doffer-rollers D is provided with bearings J, in which itsshaft S is arranged to turn and slide horizontally, but one of thesejournal-bearings J be ing shown, as both of them are the same inconstruction. The doffer D is provided with a shaft S turning injournals J 2 and adapted to be moved horizontally therein, but of which,both bearings being alike, only one is shown.

The letter I designates a vertical bar which at its upper end connectswith the shaft S and at its lower end with the shaft S in such a mannerthat the shafts S and S may turn in said bar I.

The letter A designates a horizontal bar which at its inner end connectswith the ver- Serial No. 587,605. (No model.)

tical bar I at right angl s thereto, and this horizontal bar A isprovided with a horizontal slot (1 The letter B designates a verticalstandard provided with an A-forin support constructed with legs I) b andhaving a central slot S with its A-form legs firmly secured to a base.

The letter N designates a vibrating bar pro vided with a pivot-bolt nhaving a washer n and securing-nut n arranged on the outer end of saidbolt outside of its washer. The inner end of this bolt is attached tothe vibrating bar N, and the bolt 01 is passed through the slot S of thestandard A, with its washer n straddling the sides of said slot, andtherein secured by the nut n".

The letter S designates a slot formed in the upper end of the vibratingbar N, whereby, by means of a bolt a the latter bar adjustably connectswith the slot a of the horizontal bar A.

The letter d designates a shaft having journals d d in the legs b b ofthe standard B, in which the shaft 61 may turn.

The letter F designates a driving-pulley arranged on the shaft 61 fromwhich it receives rotary power by means of a driving-belt. (Not shown.)

The letters 0 designate cams arranged on the inner face of the two-partwheel lV, secured to the shaft 01 The lower end of the vibrating bar Nis arranged to move between these cams in the inner side of the two-partwheel W, and as the shaft 01 is turned these cams C engage with thelower end a of the vibrating bar N to have it weave back and forthbetween them, thus causing the bar N to vibrate 011 its pivotalconnection with the standard B by means of the pivot-bolt n arranged inthe slot S of the standard- As this bar N is thus vibrated on its pivot(acting as a fulcrum) it causes the horizontal bar A to reciprocatehorizontally, and by means of its connection with the vertical bar I andthe latter with the shafts S and S of the doffer-rollers it causes thelatter to reciprocatinglymove on their journals.

By means of the pivotal connection made between the vibrating bar N andthe standard B through the slot S of the latter and the pivotalconnection made between the vibrating barN and the horizontal bar A avaried measure of horizontal reciprocation may be given to thedoffer-rolls, and thus the colors of yarn coming from the cylinder C maybe mixed as to measure of color as desired.

Having thus described our invention, what we claim, and desire to secureby Letters Patent, is-

1. In an apparatus for horizontally vibrating doffer rollers, thecombination with a standard that is vertically slotted, and has*downwardly and outwardly projected legs provided with bearings; of adriving-shaft having a two-part Wheel mounted thereon and provided withcams on its inner surfaces; a vertically-arranged bar provided with anadjustable fulcrum connection with the slot in said standard, and itslower end adapted to be vibrated by said cams a horizontal bar making aconnection with said vertical bar; and doffer-rollers provided Withshafts on which to turn and reciprocatingly move horizontally, saidshafts connecting with said horizontal bar, substantially as and for thepurposes set forth.

2. The combination with the doffer-rollers D, and D each having thespacing-rings R, and provided with shafts having bearings on which toturn and be reciprocated horizontally, of the arm I, connected to saiddofferroller shafts; a horizonal bar A, connected to said arm I; thestandard B, provided with the slot S the vibratory bar N, adjustablyconnected pivotally to the bar A, at its upper end; the two-part wheelWV, constructed with the cams 0 on its inner surface; making a cornnection with the lower end of the bar N, and the drivin g-shaft dconstructed and arranged to be operated, substantially in the manner asand for the purposes set forth.

Signed in the presence of the two witnesses whose names are heretowritten, at Troy, New York, this 16th day of May, 1895.
